To all whom it mag concern Be it known that I, PAUL J. LAPIIAM, acitizen of the United States, residing at Genoa, Dekalb county, andState of Illinois, have invented certainnew and useful improvements inLeather-Skiving Machines. of which the following is a full, clear, andex act specification.

This invention relates to improvements in leather skiving machines fortrimming or skivingsections or parts of leather used in themanufactureof bootsand shoes and other articles, and the primary objectof the same is to provide an improved machine of this character forski'ving or trimming the sections or parts of leather to a uniformthickness.

A further object is to provide an improved machine of this characterwhich will skive or trim a section or part. of leather to the thicknessof its thinnest side, and

which will be automatically set by the insertion into the machine of thesection or part of leather to be skived.

A further object is to provide. an improved machine of this characterwhich may be automatically adjusted bythe insertion of the section orpart of leather to be skived, and which will be locked against furtheradjustmentwhile the latter is in the machine.

A further object is to provide a machine of this character containing animproved means for identifying or marking the sec tions or parts ofauniform thickness.

-To the attainment of these ends and the accomplishment of other new anduseful objects, as will appear. the invention consists in the featuresof novelty in the. constructicn, combination and arrangementof theseveral parts hereinafter more fully described and claimed,-a11d shownin the accompanying drawings illustrating an exemplification of' theinvention. and in which Figure 1 is a longitudinal sectional view of themachine constructed in accordance with the principles of this invention.Fig.

Referring more particularly to the drawings, the same reference numeralsdesignate similar parts throughout the several views. In thisexempliiication of the invention, which will now be described as a bootand shoe sole skivi'ng machine, the numeral 20 designates two uprightsupporting standards, suitably spaced from each other. J ournaledbetween these standards at a convenientheight from the base thereof andin suitable stationary bearings, is a roller 21. Secured to the shaft ofthis roller 21, preferably on the outside of one of the standards 20, isan operating gear-wheel 22. Located above the bearings of the roller 21are bearings 23 which are preferably pivotally supported in anadjustable frame 24 by means of suitable trunnions 25. A roller 26 issupported by a frame 27 between the standards 20, and the extremities ofthe roller 26 are journaled in the bearings 23, in such a position thatthe roller 26 will be spaced slightly above the roller 21 and paralleltherewith. The adjustable frame 24 is provided with a slot or aperture28 opening through the top thereof, and in which the top of the frame 27is located, and the upper face of this frame 27 is preferably recessedor grooved as at 29 to form a track or way for a purpose to behereinafter set forth. The adjustable frame 24 is preferably providedwith shoulders 30 which extend over and in the path of the upwardmovement of the bearings 23 and. against which the said bearings abut,when the roller 26 is raised. An operating gear wheel 31. is secured tothe shaft of the roller 26, preferably on the outside of the standard 20opposite the gear wheel 22 of the roller 21. 'i

A- suitable member 32 is arranged for sliding movement between thestandards 20 above the roller 26, and said member is provided with aforwardly projecting flange 33. A carriage 34 is provided with arecessed portion adapted to receive the flange 33 of the member 32. andsaid carriage is held in position with relation to the member 32- bymeans of the removable section or portion 36, which is provided with aprojecting flange 37 adapted to enter a similar recess 38 in thecarriage iit and on the opposite side thereof. The flanges ii -l and 37are preferably arranged in line with each other and the said member 36is spai'etl from the member 32 by means of the sparing block 39, and isheld in position in any suitable manner, preferably by means of the boltor screw 40 passing through the member 36 and into the spacing block ormember 39. This spacing block or member 39 preferably located at a pointintermediate the top and the bottom of the member 86 and is spacedslightly above the top of the arriage 34. v

The adjacent faces of the carriage 3t and the spacing block or member 30are provided with recesses 41, 42, which coiiperate with each other toform a race-way for suitable anti-friction balls or rolls 43. Journaledin the bottom of the carriage 34 and in position to rest and move in therecess or groove 29 is a suitable roller 44.

Secured to the member 32 above and spaced from the member 36 is abloel;or member 45, which is held in position in any desired or suitablemanner, such as by means of bolts or screws 46 passing through thesliding member 32 and into the block or member 34. A rack or member 4-?supported for independentmovement by the member 32 in such a positionthat the lower extremity thereof will. preferably standbetween themembers 82 and 36. A suitable yielding member, such as a spring 48, isdisposed between the rack or member 47 and the spacing block or member39, and servesto normally hold the rack or member 47 raised in suchposition that the upper end thereof will abut or engage the block ormember .25; and the upper end of this rack or member 47 is held fromdisplace ment in any suitable manner, prefcrahlyby means of anoverhanging lip or flang 49 on the block or member 45.

The sliding member 32 normally held in such a position that the roller26 wiltbe in close proximity to the roller 21, by means of a suitableyielding member 50, such as a coil spring or the like, onevend of whichpreferably rests upon the upper edge of the bloelc or member 45 and theother end engages a suitable flange or collar 51 on an adjusting screwor bolt 52 which preferably passes through the uprights or standards 20.By adjustingthis screw or bolt 52 the tension of the yielding memher orspring 50 may be varied, as will be understood, and said screw or boltis held in its adjusted position in any suitable manner, preferably bymeans of a jam nut 53.

Located preferably slightly in advance of the uprights or standards 20and spaced from each other, are similar uprights or standards 54. Thesetwo pairs of standards are connected to each other inany suitablemanner, preferably by means of spacing side bars 55. Suitable bearings56 are mounted for sliding movementin the stand ards 54, and journaledin these hearings is a roller '57. These bearings are yieldinglysupported by means of a spring or yielding member 58, one end of whichengages the bearings 56 and the other end rests upon a suitable support59 on'the standards 54, a suitable rod or bolt 60 being secured to thebearing 56, and passing through the spring or member 58 and the supportor projection 59, and said rod or bolt may be held in its adjustedposition by means of the jam nut 61. Bearings 56 are supported betweenthe standards 20 by yielding members or springs 58, so that the normalposition of the roller 57 will be slightly above the correspondingroller 21 located between the standards 20. A suitable operating gear 62is secured to the shaft of the roller 57, preferably on the outside ofone of the standards 54, and in line with the operating'gear 22 ,of theroller 21; and located between these two gears 22 and 62 is a pinion 63which is secured on a driving shaft 64, and which meshes with the twogears 22, 62, for transmitting a rotary motion to the rolls 21 and 57when the driving shaft is operated. Mo-

Thus if it is desired to skive a piece ofleather of suificient thickness to produce a shoe sole of a thicknessequal to 12/48ths or 13 :t8ths of an inch, the shaft (it) would berotated by the segment 76 in a manner already set forth, until the 12thor 13th notch, as the case may be, is brought into a direct line withthe knife edge of the heads 80 of the members 78.

If the edge of the heads 78 should strike the inclined sides of any oneof the notches, it will beforced into that notch or recess causing thesole to be skived to the thickness represented by the said notch.

With a machine of this construction, boot and shoe soles of varyingthickness may be skived from a single stock or assortment, and as thesoles pass through the machine they are deposited, as usual, in a commonpile. \Vhen it is desired to sort the soles it has usually beenaccomplished by some one measuring the various soles and sorting themaccording to lot or thickness. In order to obviate this task ofmeasuring each of the soles, and to identify or mark each of therespective soles as it passes through the machine so that they may beeasily assorted by their identification number or mark, a suitablemarking or identifying means, which will now be described, is employedin con nection with this machine, and is automatically operated by therespective sole as it passes thercthrough, the same not being hereinclaimed specifically, as it forms the subject matter of a divisi nalapplication.
